Typical USB flash drive troubleshooting

Fault description: the USB flash drive is divided into two partitions that cannot be merged. In device management, two physical drives are displayed. Only one public partition can be accessed on the system without UFD encryption, or the system (98, 2000, Xp) cannot be identified at all. The main reason is that the UFD encryption program divides the USB flash disk into two parts: a public partition and an encrypted partition. You can only access public partitions without a correct access password or on a system without a UFD program installed to protect private data. Many of my friends think that the fault is caused by hardware faults. In fact, Flash Memory has a long life and is said to be able to erase more than 1 million times, even if the lifetime is only one of the nominal values (0.1 million times), it may take nearly three years for us to read and write 100 times a day. Therefore, if you encounter a USB flash drive failure, do not give up easily.
The UFD encryption software only has the partition function, but does not provide the partition deletion and merging function. After searching the network, it cannot find a ready-made partition merging software. By trying to find an alternative method, you can completely delete the encrypted partition and restore it to the initial capacity. The method is as follows:
(1) install the UFD driver and encryption program;
(2) Insert a USB flash drive, and enter the default password "0000". The unlock icon will appear on the system tray;
(3) Right-click the icon and select "split secret area ";
You can use the ufdself-contained mformat.exe formatting tool. Otherwise, it will be divided into two partitions!
